Diffusion Tensor Imaging Tracks Chronic Traumatic Brain Injury
On July 21. 2014, researchers from the Center for BrainHealth at The University of Texas at Dallas published a study in the Journal of Neurotrauma, seeking to correlate the appearance of white matter damage from TBI with cognitive problems. Using the technique known as Diffusion Tensor Imaging (DTI) the researchers found that as patients’ white matter tracts healed their cognitive processing speed increased, while patients with chronic white matter damage continued to show slowed cognitive processing speed. The DTI imaging and cognitive testing were done twice, one day post TBI and again seven months post TBI.
